Answer:
cost of 3 tables is Rs 3300
cost of 5 chairs is Rs 3000
Step-by-step explanation:
let the cost of a chair =x Rs
cost of 5 chairs is 5x Rs
then cost of each table =(x+500) Rs
cost of 3 tables is 3(x+500)Rs
so,
3(x+500)+5x=6300
=> 3x+1500+5x=6300
=> 8x=6300-1500=4800
=> x=4800/8=600
cost of one chair is 600 Rs
cost of 5 chairs is 600×5Rs=3000Rs
cost of one table is (600+500)Rs=1100Rs
cost of 3 tables is 1100×3Rs=3300Rs
